Overcurrent circuit breaker, 6kA, B characteristic, 3-pole, 63A MBN363E

Three-pole overcurrent circuit breaker – reliable installation protection

This Hager MBN363E three-pole overcurrent circuit breaker is a key element of every safe electrical installation. Designed to protect circuits against overloads and short circuits, it provides reliable operation in both domestic and industrial conditions. Characteristic B makes it ideal for circuits with devices with high inrush current, such as motors or transformers.

Functionality and technical parameters

The MBN363E circuit breaker with a rated current of 63A and a short-circuit breaking capacity of 6kA (according to EN 60898) effectively protects the installation against the effects of sudden overvoltages. The rated short-circuit capacity Icu at 400V is 10kA, which further increases the level of safety. The device's design allows for flush mounting, and its width of 3 modules makes it easy to integrate with existing distribution boards. Conductors with a cross-section from 1 to 35 mm² (solid) or from 1 to 25 mm² (stranded) can be easily connected using screw terminals.

• Overload and short-circuit protection: Protects the circuit from damage caused by excessive load or short circuit.

• Characteristic B: Provides a quick response to overloads and short circuits, but allows for short-term current surges, which is important when starting devices with a motor.

• Short-circuit breaking capacity: 6kA according to EN 60898 and 10kA according to IEC 60947-2 – a high value guarantees effective disconnection of the circuit in the event of a failure.

• Flush mounting: Allows for aesthetic and discreet placement of the circuit breaker in the wall or other structural element.

• Width of 3 modules: Compact dimensions allow for easy integration with existing distribution boards.

• Operating temperature range: From -25°C to +70°C – ensures reliable operation in various environmental conditions.

User comfort and innovative solutions

The Hager MBN363E circuit breaker is distinguished not only by its technical parameters, but also by its well-thought-out design and additional functions that facilitate installation and diagnostics:

• Innovative vertical comb busbars: Enable quick, easy and safe connection between devices in the distribution board.

• Labeling field with a protective flap: Allows for clear and aesthetic labeling of devices, which facilitates identification in the event of a failure or maintenance.

• IP2x touch protection: Ensures user safety, even during maintenance work.

• Possibility of additional equipment: Compatibility with various accessories (release trip units, auxiliary contacts) allows you to adapt the circuit breaker to specific installation needs.

• Double mounting clips: Facilitate the removal and replacement of the circuit breaker without the need to unscrew neighboring devices (for the 10 kA version).
